AuCu alloy particles were prepared by the vacuum evaporation technique and studied by means of high resolution electron microscopy. The structure of ally particles iust after the deposition was, in general, the ordered structure, AuCu I, and the heat treatment was necessary to obtain AuCu II phase. The simultaneous evaporation technique was more favorable to grow AuCu II particles than the successive evaporation technique. With decreasing particle size, the formation of AuCu II phase turned out to be difficult, and for particles around 100 Å in 200 Å in diameter, only a portion of AuCu I particles transformed to AuCu II particles. For small AuCu II particles, the distortion of the antiphase domain boundaries and the lattice planes at the periphery of particles were observed through the dark field images the lattice images, besides a zigzag nature of the antiphase domain boundaries.
